I don't haggle. At all. I've sold a startup before for 7 figures. You know how I closed deals with Fortune 500 companies when we were selling our product? "Here's the price. Please feel free to shop elsewhere if you're not interested." Same with selling the shop. "Here's the price (based on our fundamentals). If you don't want to buy it, cool, someone else will. Or it can keep printing us cash."
Haggling is overrated.
